TAIWAN: From now until mid-autumn, it is the white shrimp harvest season, but affected

by the continuous heavy rains in the south, the shrimp farming water quality environment in Chiayi County in southwest Taiwan is seen affected, causing illness or death, which has caused 10 to 30% losses.

The white shrimp that have just been harvested have changed color. Some of them have even died. The aquaculturists said that the heavy rain of this time has caused the shrimp pond water quality to decrease and become acidified, which caused many white shrimp to die of diseases, so they also greatly reduced their harvest.

In the past, 2.5 hectares cultivated, approximately 11,000 to 14,000 kilograms, but now it is less than 3 kilograms. White shrimp farming in Chiayi is mixed mainly with other fish species, and water quality cannot be changed with a single offspring. It is easy to affect the growth of white shrimp. According to the Fishing Association, the white shrimp harvest at the height of 4 or 5 years ago can reach more than 8,000 tons. Heavy rains this year, combined with a low reproduction rate, only exceed 2,000 tons compared to the same period last year.

President of the Chiayi County Fish Breeding Association, said: "In the case of this rain wave, the estimated loss of the entire white shrimp industry is ten to thirty percent. It is very likely that many fishermen are psychologically prepared but it will be very difficult to make money this year with the shrimp. "

Farmers said that to avoid deterioration of shrimp disease in the ponds, they should go to the afternoon to save and choose the bad shrimp. As heavy rains are planned they can only take advantage of time and hurry to reduce some losses.
